Packing for a romantic weekend away is, I think, all about nice textures. Stylish comfort is key. Weekends away with your love are not the time for high-maintenance glam, as the point is to spend less time in the bathroom or in front of a full-length mirror and more time with him or her.
Bring one pair of high heels and one pair of cute patterned flats for day-time.
Comfy trousers are nicer to travel in than restricting jeans.
A couple of dresses can be worn day and night with different shoes and tights.
A sweater or two in a soft cashmere or angora wool is utterly touchable.
